"I" is not accepted as subject in MATLAB

What steps will reproduce the problem?
1. Set classpath.txt in Matlab
2. Use following code
   import simplenlg.framework.*
   import simplenlg.lexicon.*
   import simplenlg.realiser.english.*
   import simplenlg.phrasespec.*
   import simplenlg.features.*
   lexicon = Lexicon.getDefaultLexicon();
   nlgFactory = NLGFactory(lexicon);
   realiser = Realiser(lexicon);
   p = nlgFactory.createClause('I', 'be', 'happy')
   output4 = realiser.realiseSentence(p)
3.

What is the expected output? What do you see instead?
I get "I am Happy." as output in Java. But Matlab gives following error.
??? Java exception occurred:
java.lang.IllegalArgumentException: I is not a valid type
